Document Type and Number:
WIPO Patent Application WO/2019/083239
Kind Code:
A1
Abstract:
The present invention relates to a DC commutator motor winding structure comprising: a core (10) having K teeth (T) formed thereon radially; a commutator (20) which is coupled to the upper portion of the core (10), and which has K commutator pieces (C); a shaft (30) configured such that the core (10) and the commutator (20) penetrate the same and are coupled thereto so as to rotate together; and multiple magnets (40) installed to face the core (10), wherein the K teeth (T) comprise first to Kth teeth (T1 to TK) successively, and the K commutator pieces (C) comprise first to Kth commutator pieces (C1 to CK) (wherein K is an even number equal to or lager than 16); a coil wired to a commutator piece serving as a start point is primarily wound at [S(n), S(n+4)] and then is secondarily wound at [S(n+9), S(n+13)]; after being wound secondarily, the coil is wired to a commutator piece serving as a routing point in the reserve direction and then is wired to a commutator piece serving as an end point; and the coil repeatedly undergoes the above winding process [wherein n is a natural number of 1 to 18 and, when any value of (n), (n+4), (n+9), (n+13) exceeds K, the remainder when the exceeding value is divided by K is used as n].
